'Biggest Loser' star motivated by cast photo

Biggest Loser eliminee Ana Alvarado has revealed that she visualizes her publicity photograph for the NBC show when she needs extra motivation in the gym.

The 50-year-old was voted off the competition's eleventh season on Tuesday night after falling below the yellow line with daughter Irene.

She told Digital Spy that she had initially felt "depressed" when she returned home from the ranch but was inspired by the promise she had made to Irene before leaving that she would change her lifestyle.

She has since started going to the gym, forming exercise groups with her friends and controlling what she eats, which includes avoiding her previous weakness of fast food.

She added: "Sometimes when I'm at the gym and bored to death and thinking, 'Oh God, I don't want to do this!'. I keep visualizing the promise I made my daughter but also how I looked in that bright orange shirt with those biker shorts and everything hanging out and think, 'I am going to look different at finale!'."

Portland resident Alvarado, who has lost around 50lbs from her starting weight of 255lbs, added that she hopes to lose another 50lbs before finale and that she would ideally like to shed around 120lbs in total.
